This is only one of the many advantages of the new tape- 

 recorded Acoustiguide tours now available at the Museum. 

 Your Acoustiguide is a small, tape playback machine, which 

 is carried on a strap around your neck and fitted with a feather- 

 weight earphone. It replaces the Museum's former radio 

 transmission guide system. Two pre-recorded, 45-minute 

 tours are offered: one on the story of mankind (through the 

 anthropology exhibition halls) ; the other on the world of na- 

 ture (through halls devoted to geology, botany, and zoology). 

 The tours are prepared and authenticated by the Museum's 

 scientists and educational staff; the voice you hear is that of 

 a professional narrator. Each tour costs 50 cents; or, for 75 

 cents, two persons may share a recorder equipped with two 

 earphones. Acoustiguide tours may be taken completely at 

 your own pace, interspersed, if you like, with periods of rest, 

 independent study, or refreshment. 



We invite you to come in soon and take advantage of this 

 technological advance that can make your next Museum visit 

 more enjoyable and meaningful than ever before.  (prn) 



Miss I)a£mar Pultz, a young visitor from Germany, turns the 

 voice of her Acoustiguide louder to hear: "Horses were the prized 

 possession of the Plains Indians. They were used in the hunt, on 

 the warpath, and also as the moving van to transport the camp 

 from one site to another. . . . This operation was, of course, the 

 responsibility of the women of the trihe."

"North of the Circle" 



Finn Ronne 



During the International Geophysical 

 Year, Captain Finn Ronne, USNR (ret.), 

 capped his distinguished career as a po- 

 lar explorer by accepting the post of 

 military commander and science leader 

 of the Ellsworth Station in Antarctica. 

 He is equally at home north of the Arc- 

 tic Circle. Ronne was with the first 

 United States task force to undertake 

 the building of airstrips and weather sta- 

 tions in the Canadian Arctic and along 

 the northern shores of Greenland. Later 

 he returned to film Eskimo life in Green- 

 land and to organize trips to the Norwe- 

 gian and Soviet Arctic stations on Spits- 

 bergen. His fine color film covers all 

 these explorations. We gain an inti- 

 mate insight into Eskimo life, and share 

 the drama as men of science battle the 

 forces of nature to extend man's knowl- 

 edge of his environment. There is add-
